I have the 3 qt. with electric valve. Hot, I bring the rpm up get the max fill and PSI and shut off the valve, then the engine. Cold test, with the valve covers off, turn on the valve, within a few seconds oil at the rocker shafts. Normal cold startup switch on, PSI to 30-40, then when starts to fall off, then start engine and into staging lane.
Canton requires #10 line.
I have mine on the left apron, maybe gets some oil cooled outside the engine for a bit. I have it mainly for dry starts, any other pressure maintaining is a good thing.
An option for road race guys  a pressure valve  that opens at specified setting. to keep pressure up.
Many sanctioning bodys require a stock type wet pan, so this helps.
If you don,t like /believe in these, then don,t use/ buy them. Nice Mustang you have there.

Updated performance numbers and vehicle weight. First good test on a good track this year,  the only upgrade/change from last years numbers were the installation of Jays water pump adapter and the CVR water pump and spall dual 11" fans, from a Edelbrock  w.p. and a semi flex fan. Before it was 10.675 @ 125.25, for a few years, now 10.584 @ 126.25. Seems to rev quicker, maybe some due to weather/ track, but stiil a good gain. Temperature control was right on.

Got to try out Jays adapter with the CVR 55 gpm pump, Spal twin 11 " electric fan/shroud,Griffin radiator, 160 deg therm. Works great, primary fan on with pump stays at 160 deg, going to the line. Sec fan on with 185 sensor was at 180 deg on gauge ,  after a run on return road, then idling in pit with hood closed. So far no creaping temp. at idle. Nice job Jay. 75 deg day here in north central Ill. Sat.
